The RT™ Max Muscle offers growers the ultimate in strength and versatility. With straight sidewalls from 4' to 10' tall makes it is an excellent choice for natural ventilation. The RT™ Max Muscle is framed using 2" x 4" column posts, 2" x 3" rectangular bows and 1" x 2" rectangular cross trusses. Growers take advantage of the extra square footage gained by using the 30' or 35' clear span width. The RT™ Max Muscle is widely used by wholesale, hydroponics and transplant growers. Additionally, the sides and/or ends can be equipped with polycarbonate to make an outstanding and attractive retail sales center.
